I am trying to automate the translation of a huge base of Pascal source
code from one dialect (MetaWare) to another (FreePascal).
One change I need to make is to modify comments like this:
-- This is a comment
To this
// This is a comment
My current rule looks like this:
SL_COMMENT_2
: '--' (options {greedy=false;} : . )* '\n'
{$channel=HIDDEN;}
;
What's the easiest way to modify the rule so that '--' is replaced by
'//'?
I have RTFM but a working solution still eludes me.
Thanks.
